All of the above

Detailed explanation-1: -Genotypes with two alleles that are the same, i.e. ‘BB’ and ‘bb’, are known as homozygous genotypes and genotypes with two different alleles are known as heterozygous genotypes.
Detailed explanation-2: -Brown is recessive, which means brown individuals must have the genotype bb.
Detailed explanation-3: -Brown fur is dominant to white fur in a species of rabbit and is represented with the alleles “B” and “b". What are the resulting percentages of genotypes of a cross between a homozygous dominant parent and a heterozygous parent? Explanation: The answer is 50% BB and 50% Bb, as shown in the punnet square below.
Detailed explanation-4: -It’s possible for them to have a combination, or “Bb”, having one dominant brown allele and one recessive blue allele. In this case, because brown is dominant over blue, they will have brown eyes.
